ABOUT YOUR DISTRIBUTION AMPLIFIER 2
The DA1226AT is a 1-in 6-out RGBHV distribution
amplifier designed to allow the connection of a
single computer video or interface source to as
many as six monitors or projectors capable of
handling the source resolution.
The DA1226AT offers excellent bandwidth
performance (minimum 350 MHz) and a typical
bandwidth of nearly 450 MHz, allowing it to remain
virtually transparent to high resolution signals.
Though primarily designed to pass an RGBHV
signal format, the DA1226AT can also pass RGBS,
RGsB, Component Video (Y, R-Y, B-Y), S-Video
(Y/C), and Composite Video by using the
appropriate channels. The DA1226AT outputs the
same sync level as it receives on its input.
The DA1226AT offers a low-profile design, which
helps to prevent tilting due to cable drag when
used in desktop applications. The DA1226AT uses
an internal 90-140/200-240V switchable power
supply. It may be rack-mounted using optional
hardware.
